The invention relates to a roller (1) with preferably two wheels (2) and a locking device. An acting part (10) can act on the locking device for releasing or locking in a position that corresponds to a directional lock and/or in a position that corresponds to a total lock. The acting part (10) can be moved by a drive, wherein a transmission part (7) linear movement that is generated by the drive is transmitted onto the acting part via spring force in order to move the acting part (10). In a position that corresponds to the total lock or in a position that corresponds to the directional lock, the acting part (10) can additionally be moved relative to the fixed transmission part into a release position against a spring that is mounted on the transmission part by means of an actuating handle (11), which is independent of the drive and which is preferably movable by hand, in order to override the total lock or the directional lock. The aim of the invention is to provide a roller that is favorably designed with respect to an emergency release. This is achieved in that a geometric rotational axis (d) of the actuating handle (11) is arranged on the same side as the acting part (10) with respect to the rotational axis (D) of the wheel (2), said acting part being arranged in a vertical section offset from the rotational axis (D) of the wheel (2).
